Hi,
I have an issue setting up datasource for my entity manager factory under spring.

spring config xml
=========================
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver" />
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/nbl" />
<property name="user" value="********" />
<property name="password" value="*******" />
<property name="maxPoolSize" value="10" />
<property name="maxStatements" value="0" />
<property name="minPoolSize" value="5" />
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">

<property name="persistenceUnitName" value="NBL" />
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter">
<bean
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="false" />
<property name="generateDdl" value="true" />
<property name="database" value="MYSQL" />
</bean>
</property>
</bean>

Exception
===========================================
i am seeing this error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource

Caused by: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [com.mchange.v2.c3p0.ComboPooledDataSource]

at org.springframework.beans.BeanWrapperImpl.convertF

LocalEntityManagerFactoryBean does not seem to have a datasource property
how does this get set up in spring?

Try something like this ...

Persistence.xml


applicationContext.xml (not full, just relevant parts)



jdbc.properties for the PropertyPlaceholderConfigurer
